LEAD OR CRAYON HOLDER.

sPEcIFIcATIoN forming part of Leners' Patent No. 276,543, dated April 24, 1883.

Application filed June 14, 1882. (No model.)

To allzu/1.0m it may concern.-

Be it known thatI, RICHARD W. UHLIG, of the city, county, and State of New York, have invented certain new and useful Improvements in Lead or Orayon Holders, of which the following is' a specification.

The object of my invention is to provide some means by which the lead in lead and crayon holders of the kind known as Autoio matic7 shall be prevented from dropping from the case or sheath more than a definite predetermined distance Iwhen such lead is released from thecontrol ofthe clamp or grasping contrvance by which it is held, or, in other words, to provide a check or stop gage which shall limit the extent to which the loose lead may drop and protrude from the pencil.

The invention is applicable to all forms of lead and crayon holders in which the lead,

zo when released from the control of the clamp or grasping contrivance, is free to drop from the pencil, so as to protrude therefrom farther than is desirable or necessary for writing purposes; and it may be carried into eect in many dierent ways.

In the accompanying drawings I have represented my check or stop-gage device applied to alead orcrayon holder now generallyknown in the market as the Automatic.

3o Figure l isan elevation of the front portion of the holder with the tip or nozzle partly removed in order to disclose lthe parts within. Fig. 2 is a longitudinal central section of the same in a plane at right angles to the plane of elevation in Fig. 1.

In the drawings, A is the case or sheath,

terminating in the usual tip or nozzle, a, and B is the longitudinally-movable lead-containing tube, terminating in expanding springjaws b. These parts are of thecustomary construction. I have not deemed it necessary to represent the pressure-cap at the rear end of the caseto which the tubeis usually attached, or the retracting spring which operates to 4 5 move the tube in a direction opposite to that in which it is forced by hand-pressure applied to the pressure-cap. The constructionand arrangement of these parts are well known, and require no further explanation.

That portion of the lead-tube within Vthe tip or nozzle is cut away on opposite sides, so as the lead x may be reached. Loosely encircling the lead-tube is a ring, d, provided on opposite sides with springing lingers or lips e,I which are situated in the slots c, and clasp between them with slight pressure the lead. The ring can travel back and forth asfar as permitted by its lin gers, whichbring up against one end or the other of the slots c. When at the rear end of the slot the lead is retracted, as shown in Fig. l. When the lead-tube is pushed forward, the pencil being held point downward,thejaws b expand, and the checkring, together with the lead, drops until the ring brings up against the front end of the slot, as indicated in Fig. 2, in which position the lead protrudes from the jaws fareuough for writing purposes. When after this the tube is drawn back by theretracting-spring, thejaws I) close on the lead andthe pencil is ready for use.

The arrangement of the check-'ring can be very considerably varied. It forms in effect a shoulder on and moving with the lead, which, by bringing up against ashoulder or stop on some suitable part of the pencil, prevents the lead from dropping beyond a prescribed distance. The ring is movable on the lead, and can be adjusted as the lead` wears away. The end of the fingers or lips c can be beveled `or turned a little outwardly, if desired, so as not to interfere with inserting alead into theleadtube.

The above is one form of lead check or stop gage which may be combined with and used in a lead and crayon holder, but the same eil feet can be produced in many different ways, and by Widely varying mechanical contrivances and expedients, which will suggest themselves to others acquainted with the art to which my invention pertains. Uonseq'uently check or stop gage herein described in illustration of my invention.

I do not claim, broadly, the application to a lead or crayon holder of a stop-gage for limiting the extent to which the loose lead can drop from the pencil; but

What I claim as new and of my own invention is to form at these points slots c, through which A check-ring loosely surrounding the leadl I do not restrict myself to the special form ot' IOO tube and provided with spring-fingers for In testimony whereof I` have hereunto set clasping the lead, in combination with the my hand this26th day of May, 1882. lead grasping and releasing mechanism, the

sheath, and a stop or shoulder on or in lshe RICHARD W UHLIG' 5 holder for limiting the forward movement of lVitnesses:

the check-ring, substantially as hereinbefore LEOPOLD AUsBAoHER,

set forth. SAMUEL KRAUs.
